' IMPROVEMENTIN CLEARER- ROLL SUPPORTS FOR SPlNNING-FRAMES.

Speeifieation formingpart of Letters Patent No. 191,586, dated June 5,1877; application filed January 20, 1877.

To all whom it may concern:

Be it known that I, FREDRIG B. HART, of Bristol, in the county ofBristol and State of Rhode Island, have invented certain new and usefulImprovements in Clearer-Roll Supports; and I hereby declare that thefollowing is a full, clear, and exaet description of the same, referencebeing had to the aecompanying drawings, forming part of tlisspecification:

Figure 1 is a front view of one of the delivery-rolls'of aspining-frame, showing the clearer-roll snpporter on the yieldingspringpressed levers. Fig. 2 is a view of my improved clearer-rollspring and the standard by which the same is supported.

This invention has reference to improvements in the yielding support forthe clearerroll used in spinning-frames, under the delivery-rolls, forthe purpose of clearing the delivery-rolls of. all waste, so as toprevent the lappin g of the same on the delivery-rolls; and consists inthe novel arrangement of substantial hinged levers, provided at theirfront ends with bearings for the clearer-roll, their rear ends beingconnected by rods with spiral springs, arranged to keep the clearer rollagainst the delivery-roll, and allow the same to yield as it becomesfilled with waste, and

also when it is taken out or replaced.

It further consists in providing a separate standard to support theyielding levers, and also eontain the coiled Springs, by which theclearer-roll is pressed against the deliveryroll.

In the drawings, a is the delivery-roll. b represents the elearer-roll.c c are the hinged levers, aranged with bearings for the clearerroll,and supported at d. e is the rods, connecting the rear ends of thelevers c c with the coiled springs f. gis the arm supporting the fulcrund. l' is a bracket, provided with a hole, that the standard may besecured under the rail k by the nut, with which the posts i z' aresecured to the rail K.

If desired, the standard may be secured to the rear of the rail k at f',or in any other convenient manner.

Olearer-roll springs, as heretofore constructed, have usually consistedof thin metal springs secured on top of the posts i t'. Such springswill either be liable to bend, and lose their elasticity sufficient toallow the clearer-roll to press imperfectly against the delivery-roll,and thus allow the waste to lap on the same, or when sufficiently stffthey are liable to break and cause stoppage and loss of time, as therolls and bolsters have to be removed to replace the springs, ad suchsprings also bear too hard on the rolls, when the clearerroll is partlyfilled with waste and the diameter enlarged.

My improved clearer-roll springs are strong and durable. They can besecured to the frame or taken off without removing the rolls or thebolsters. They hold the clearer-rolls firmly and uniformly up to thedelivcry-rolls. They allow the taking out and replacing of the clearer-rolls without danger or injury, while the coiled Springs, beingcontained in the standard and protected, are not liable to catch andhold the waste, as is the case with the older style of springs.

Olearer-rolls have been supported on hinged arms, provided with weightsto counterbalance the weight of the roll, and press the same against thedelivery-roll, but such weighted arns press the clearer-roll withdiminishing force as the same increases in diameter, while the coiledspring in my invention increases the pressure with the increase of wasteon portions of the clearer-roll, and thus prevents lapping at pointswhere less waste has accumulated.

Having thus described my invention, I cl'aim as new and desire to secureby Letters Patent 1. The combination, with the standard gf', arranged tosupport the levers c, and contain the coiled Springs f, with the hingedlevers c, rods e, and springs f, ali arranged to support theclearer-roll of a spinning-frane, substantially as and for the purposeset forth.

2. The combination, with the standard gf', arranged to support thehinged levers c, of the bracket h, arranged to secure the standard tothe spinning-frame, substantially as and for the purpose specified.
